RISK

Why read_raycast is rated Low

This tool retrieves information about RayCast and ShapeCast nodes in the Godot scene tree. It performs a read-only operation (listing/querying) with no capability to modify, execute, or delete data. The 'read' prefix and 'List' verb confirm the informational nature of this operation.

From the tool's definition Tool name 'read_raycast' and description 'List RayCast/ShapeCast nodes' indicates querying/listing existing nodes without modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs read_raycast safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For read_raycast, this is the rule to start with:

read_raycast Allowed

read_raycast is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "read_raycast": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every read_raycast call is checked against it from then on.
